Industrial-strength liquid chlorine
for every application.
HASA Multi-Chlor — also known as Purple Sani Chlor, Purple Chlorine, and Multi-Chlorine — is a high-purity 12.5% sodium hypochlorite solution NSF/ANSI 60 certified for safe, regulated use across agriculture, food processing, aquaculture, potable water, irrigation, and industrial sanitation.
✓ NSF/ANSI 60 Certified ✓ 12.5% Sodium Hypochlorite ✓ Food-Contact Safe ✓ Potable Water Approved 12.5% Available Chlorine ~12.5 pH Level 6+ Industries Served What sets it apart
Not your standard pool chlorine.
Standard pool chlorine is formulated for one job. HASA Multi-Chlor — widely known as Purple Chlorine or MultiChlor — is engineered to meet the strict purity and safety standards required across food handling, potable water, crop production, and regulated industrial environments.
Its NSF/ANSI 60 certification means it has been independently tested and verified safe for contact with drinking water, fresh produce, aquaculture systems, and food processing surfaces — applications where standard pool chlorine simply is not approved.
🏅NSF/ANSI 60 Certified — independently verified safe for potable water, food contact, and regulated applications where standard chlorine is not permitted. 🌾Crop and produce safe — approved for fruits, vegetables, seeds, and hydroponic systems within allowable ppm guidelines. 🐟Aquaculture grade purity — stable 12.5% concentration trusted in fish ponds, hatcheries, and recirculating systems. 💧Potable water approved — suitable for well shock chlorination, cisterns, storage tanks, and emergency disinfection. 🏭Industrial versatility — from irrigation biofilm control to rooftop mold removal, Multi-Chlor handles environments most products cannot. Applications
One Multi-Chlor. Every industry.
Whether you call it Purple Sani Chlor, Multi-Chlorine, or MultiChlor — the applications span nearly every industry that requires controlled, certified sanitation.
🌾 Agriculture & Crop Management Used for rice seed disinfection, greenhouse sprayer sanitation, hydroponic cleaning, produce wash systems, and bee equipment sterilization. Multi-Chlor meets crop-contact purity standards where generic chlorine cannot be used. Rice seed soaking1,500–3,000 ppm Produce wash water25–200 ppm Greenhouse irrigation1–2 ppm 💧 Irrigation & Drip Line Sanitation Irrigation lines accumulate algae, iron bacteria, and organic buildup. Purple Chlorine oxidizes biofilm and maintains line performance in drip systems, pivot lines, and greenhouse setups. Continuous dosing1–2 ppm Shock treatmentUp to 20 ppm Seasonal line flushAs needed 🥦 Food Processing & Produce Sanitation NSF 60 certification makes Multi-Chlorine the preferred liquid sanitizer for packing houses, coolers, and processing facilities. Used in hydrocoolers, spray bars, CIP systems, and rinse tanks. Fruit & veg wash25–200 ppm HydrocoolersPer facility spec CIP sanitationPer facility spec 🐟 Aquaculture & Fish Pond Operations Purity and stable concentration make MultiChlor trusted across hatcheries, recirculating aquaculture systems, oyster conditioning, and pond prep. Reduces biofilm and maintains healthy tank environments. Pond sanitation~10 ppm Equipment soaking200 ppm Oyster conditioning0.5 ppm 🚰 Wells, Cisterns & Potable Water One of the few chlorine products certified safe for drinking water. Purple Sani Chlor is used for well shock chlorination, storage tank sanitation, post-flood treatment, and emergency disinfection per label guidelines. Well shockPer label Storage tanksPer label Emergency useDrop-per-gallon 🏭 Roofing, Industrial & Marine Multi-Chlor handles the heavy-duty applications too — asphalt and cedar roof mold, marine hull treatment, concrete and deck sanitation, cooling tower microbial control, and beach disinfection. Roof mold/algae~5,000 ppm Boat hull slime~35 ppm Cooling towersPer system spec Simple dosage. Consistent results.
HASA Multi-Chlor’s consistent 12.5% concentration makes dosing predictable and repeatable across every application — from pool maintenance to agricultural sanitation to industrial use.
Available in disposable one-way containers. Store cool, shaded, and ventilated. Keep sealed and upright until use.
10 fl oz of 12.5% Multi-Chlor raises 10,000 gallons of water by 1 ppm — a reliable, consistent baseline for any application. “NSF/ANSI 60 certified — the standard that separates professional-grade chlorine from everything else.” HASA Multi-Chlor · Purple Sani Chlor · Multi-Chlorine · MultiChlor · Purple Chlorine Safe handling
Handle with confidence.
Like all high-strength sodium hypochlorite solutions, Multi-Chlor requires standard chemical handling precautions. Follow all label instructions for dilution, application, and disposal. When used correctly, it is safe and effective across every certified application.
Always dilute to the appropriate ppm for your use case before application. Never mix with acids or incompatible substances. Use PPE appropriate for your environment and exposure level.

Frequently asked questions.
Is Multi-Chlor the same as pool chlorine?+
Chemically similar, but not the same. HASA Multi-Chlor — also called Purple Chlorine or Purple Sani Chlor — carries NSF/ANSI 60 certification, independently verifying it safe for food-contact applications, agriculture, wells, and potable water systems. Standard pool chlorine does not meet these standards and is not approved for those uses.
Can I use Multi-Chlor for irrigation systems?+
Multi-Chlorine is commonly used at 1–2 ppm for continuous dosing, or at stronger concentrations for shock treatments depending on biofilm or mineral buildup. Use caution with chlorine-sensitive crops like tomatoes and lettuce, and always follow label guidelines for your specific crop and system type.
Is it approved for rinsing fruits and vegetables?+
Yes. MultiChlor is NSF 60 certified and widely used in food processing and packing operations for fruit and vegetable wash water at 25–200 ppm. It is one of the industry’s preferred liquid sanitizers for hydrocoolers, rinse tanks, and spray bars handling fresh produce.
Is it safe for aquaculture?+
When used at appropriate concentrations — yes. HASA Multi-Chlor is trusted in hatcheries, fish ponds, and recirculating aquaculture systems. Pond sanitation typically runs around 10 ppm; equipment soaking at 200 ppm; oyster conditioning at 0.5 ppm. Always dechlorinate before reintroducing livestock.
Can it be used for wells and drinking water?+
Yes. Purple Sani Chlor meets NSF/ANSI 60 requirements for potable water system sanitizing. It is approved for well shock chlorination, water storage tank sanitation, post-flood disinfection, and emergency drinking water treatment per the label’s drop-per-gallon method.
What is the pool dosage for Multi-Chlor?+
10 fluid ounces of 12.5% Multi-Chlor will raise 10,000 gallons of water by 1 ppm. This consistent concentration makes dosing predictable and easy to calculate for pool, irrigation, and industrial applications alike.
