Water worx™
Application Guide

Purpose and Scope
This document serves as a practical application guide for the Water Worx™ Series, translating the core product concepts into disciplined field use. It is written for agronomists, crop advisors, and growers managing salinity, sodicity, and nutrient inefficiency under modern irrigation systems.

WaterWorx products are soil-reclamation and efficiency tools, not fertilizers and not simple acids. Their value lies in how they interact with water chemistry, calcium availability, and soil exchange dynamics over time. This guide explains how to use them correctly and what results to expect.

Product Identity and Positioning

WaterWorx™ Series is a family of liquid acid-based soil and water treatment products designed for salinity management, sodium displacement, nutrient mobilization, and irrigation system preservation.

The series includes:

  • Water Worx Pro™– High-strength formulation for aggressive reclamation and heavy leaching
    • Water Worx Mid™ – Balanced formulation for seasonal salinity control
    • Water Worx LC™ – Low-dose, continuous-use formulation with ultra-low vapor pressure
    • Water Worx Storm™ – High-acid wet-season product for rainfall-assisted flushing

All Water Worx products utilize a proprietary mineral and organic acid blend engineered to work with calcium already present in irrigation water or soil.

WaterWorx products are designed to operate in systems experiencing one or more of the following constraints:

  • Sodium accumulation on exchange sites
    • Reduced water infiltration and permeability
    • Elevated soil EC and osmotic stress
    • Nutrient tie-up due to carbonate chemistry
    • Root restriction and shallow wetting patterns

These conditions commonly occur together and cannot be corrected by fertility alone.

Sodium Displacement and Cation Exchange

WaterWorx does not “remove sodium” by itself. Instead, it increases the effectiveness of calcium-driven exchange reactions by:

  • Reducing carbonate buffering
    • Improving calcium solubility and activity
    • Preventing premature precipitation of calcium salts

When followed by adequate leaching water, sodium is displaced from exchange sites and moved below the root zone.

Water Infiltration and Soil Structure

By reducing sodium dominance and localized dispersion, Water Worx supports improved soil aggregation and pore continuity. Over time, this leads to:

  • Improved infiltration rates
    • More uniform wetting patterns
    • Reduced surface sealing

These improvements are cumulative and program-dependent.

Nutrient Availability

The organic acid fraction in Water Worx chelates key macro- and micronutrients, keeping them soluble and mobile across a wide pH range. This reduces nutrient lock-up and improves fertilizer efficiency without adding nutrients directly.

Water chemistry determines WaterWorx performance.

WaterWorx products are particularly effective in waters with:

  • High bicarbonates
    • Elevated calcium hardness
    • Iron and manganese challenges
    • Scale-forming tendencies

WaterWorx dissolves existing carbonate and sulfate scale while simultaneously reducing new scale formation, extending the life of drip lines and emitters.

Water Worx Pro™

Use when:

  • Soils are severely sodic or saline
    • Aggressive leaching is planned
    • System downtime allows higher acid loading

Typically applied as a slug or short-term program.

Water Worx Mid™

Use when:

  • Managing seasonal salt accumulation
    • Maintaining reclaimed soils
    • Running structured leaching cycles

Often used multiple times per season.

Water Worx LC™

Use when:

  • Continuous low-dose injection is preferred
    • Worker safety and vapor control are priorities
    • Drip systems require constant protection

Designed for frequent or continuous injection.

Water Worx Storm™

Use when:

  • Natural rainfall is available
    • Off-season or winter leaching is planned
    • Rapid sodium movement is required

Designed to capitalize on high soil moisture and water tables.

Application Strategy and Timing

WaterWorx products are most effective when:

  • Applied ahead of or during leaching events
    • Paired with sufficient calcium sources
    • Integrated into irrigation scheduling

Reactive, single-application use rarely delivers durable results. Programmatic use produces measurable improvements in soil chemistry and crop performance.

General mixing rules:

  • Add Water Worx to water first
    • Avoid direct blending with concentrated fertilizers
    • Verify compatibility with jar testing

WaterWorx is compatible with most fertigation programs when introduced correctly.

Success should be evaluated using:

  • Soil sodium and EC trends over time
    • Tissue sodium reduction
    • Improved infiltration and irrigation uniformity
    • Reduced salt burn and margin necrosis

Field data has shown 50%+ sodium reduction in tissue over multi-year programs when WaterWorx is applied correctly.

The WaterWorx  Series provides a disciplined, scalable approach to salinity management and soil reclamation.

Used correctly, WaterWorx products restore soil function, protect irrigation systems, and improve nutrient efficiency without the handling risks associated with traditional mineral acids.

They are tools for long-term soil performance, not short-term fixes.

Cal Acid® Struvite
Control Program

Struvite (magnesium ammonium phosphate) scaling is a persistent operational issue in wastewater treatment systems, particularly in digesters, dewatering equipment, centrate lines, and sidestream piping. Once formed, struvite deposits restrict flow, damage equipment, and drive unplanned maintenance.

Cal Acid’s struvite program is designed around two complementary tools:

  • StruSolv™ R – a dissolving acid for removal of existing struvite deposits
  • StruSolv™ M – a maintenance treatment that prevents new struvite formation

Used together, they provide both corrective cleaning and long-term scale control.

StruSolv™ R Struvite Dissolver

Product Description

StruSolv™ R is a specialty acidic cleaner engineered specifically to dissolve existing struvite scale. It is formulated to penetrate hard, crystalline magnesium ammonium phosphate deposits and convert them back into soluble components that can be safely flushed from the system.

Unlike generic acids, StruSolv™ R is designed to focus its activity on struvite while maintaining controlled reactivity toward common wastewater system materials when applied correctly.

Key Benefits

  • Dissolves existing struvite deposits
    • Restores flow, capacity, and equipment efficiency
    • Effective on dense, established scale
    • Suitable for targeted clean-in-place (CIP) applications

Typical Applications

  • Digesters and digester piping
    • Centrate and filtrate lines
    • Dewatering equipment (centrifuges, presses)
    • Sludge handling and return piping

Application Guidelines

StruSolv™ R is typically applied as a circulation or soak treatment in affected areas. The product is diluted with water and allowed sufficient contact time to dissolve struvite deposits before flushing the system back to service. Application parameters are adjusted based on deposit severity and system configuration.

Product Description

StruSolv™ M is a preventative struvite control product designed to stop scale from forming in the first place. While the product contains acidic functional groups, these acids are polymeric in nature and do not behave like conventional mineral acids.

Instead of dissolving scale, StruSolv™ M works through crystal modification and dispersion. The polymeric acids interact with magnesium, ammonium, and phosphate ions at the molecular level, disrupting their ability to align, bond, and grow into hard struvite crystals.

By keeping these minerals dispersed and non-adherent, StruSolv™ M prevents them from attaching to each other and to system surfaces.

Key Benefits

  • Inhibits struvite crystal nucleation and growth
    • Keeps minerals dispersed and non-adherent
    • Reduces recurring scale and emergency cleanings
    • Enables stable, long-term operation at low feed rates

How It Works (Plain Language)

Struvite forms when individual mineral ions lock together into a rigid crystal structure. StruSolv™ M interferes with this process. Its polymeric acidic components bind and “shield” the mineral ions, preventing them from organizing into crystals. Any micro-crystals that do begin to form remain distorted, weak, and easily carried away with flow rather than attaching to equipment or piping.

Typical Applications

  • Continuous feed to centrate and filtrate lines
    • Sidestreams downstream of digesters
    • Dewatering feed piping
    • Any area with chronic or recurring struvite issues

Application Guidelines

StruSolv™ M is applied as a continuous or routine maintenance feed. Injection points are selected to ensure thorough mixing ahead of known problem areas. Dosage is based on flow rate, operating conditions, and historical struvite formation patterns.

An important advantage of controlled struvite dissolution is that dissolved struvite represents recoverable nutrients. Magnesium, ammonium, and phosphate are all valuable agricultural inputs, and struvite itself is widely recognized as a slow-release fertilizer.

By preventing uncontrolled deposition and enabling managed dissolution, Cal Acid’s struvite program supports cleaner systems while keeping nutrients in solution, where they can be directed toward recovery processes rather than becoming hard scale on infrastructure.

Recommended Program Approach

For systems with existing scale, Cal Acid recommends:

  1. Initial cleaning with StruSolv™ R to remove established struvite
  2. Ongoing treatment with StruSolv™ M to prevent reformation

This approach eliminates current deposits while minimizing future risk, improving reliability, reducing maintenance costs, and supporting long-term nutrient management goals
