HTH EASIFLO® DOSING SYSTEMS

The optimal solution for treating water in public swimming pools

HTH has developed automatic, convenient, safe, and effective systems for treating water in public swimming pools.

Each HTH EASIFLO system is based on a combination of the following 3 elements:

HTH EASIFLO BRIQUETTE are made from calcium hypochlorite and contain an anti-scale additive. Their patented formula prevents clogging in dispensers, which is a common problem with other calcium hypochlorite tablets.
A feeder called HTH EASIFLO FIRST (10, 20, 50 or 100).
An amperometric regulator, either HTH CYCL’EAU Pro or HTH CYCL’EAU First.

The combination of these 3 HTH products guarantee regulated, reliable and simple disinfection.
It enables the full and safe automation of your pool treatment. Easy to use and requiring little maintenance, it also reduces maintenance costs and the problems associated with many other dosing systems.

The HTH EASIFLO range of dosing systems is suitable for all sizes of swimming pools.
It is designed to produce a constant chlorine solution and maintain chlorine levels in public swimming pools.

EQUIPMENT & ANALYSIS

HTH pool controlers

Adopting an amperometric control system ensures automatic and effective control of your pool water. The control system automatically analyzes and readjusts the chlorine and pH levels in the pool to guarantee safety and comfort for swimmers.

In order to improve the effectiveness of treatment products and ensure optimum comfort for swimmers, it is essential to regularly check the water balance and clean the pool and check the condition of your pool filters.

The pH defines the acidity or alkalinity of water, ranging from 0 to 14, with pure water having a pH of 7. The “ideal” pH value for swimming pool water is between 7.0 and 7.4.

Water must be treated to remain disinfectant and oxidizing at all times, so it is necessary to maintain a residual level of product. Chlorine meets this requirement.

Monitoring chlorine levels is essential for public swimming pools. In France, the recommendations are as follows:

Maintain active chlorine content (unstabilised chlorine, water without stabiliser) between 0.4 and 1.4 mg/l

Maintain available chlorine content (stabilised chlorine, water with stabiliser) between 2 mg/l and 5 mg/l

Have a combined chlorine content (chloramine) of less than 0.6 mg/l.

CALCIUM HYPOCHLORITE

Why choose calcium hypochlorite?

This solution developed by HTH is recommended by the majority of pool managers who have tested the power of calcium hypochlorite.
Here’s why:

Effectively disinfecting pool water: thanks to its disinfectant action, calcium hypochlorite ensures permanent chlorination and therefore the destruction of bacteria, viruses, fungi, and algae.
Saving water: Conventional chlorine contains cyanuric acid (also known as stabiliser) which is useful for protecting chlorine from destruction by the sun’s UV rays, but in excessive concentrations it reduces the effectiveness of the chlorine and therefore the quality of disinfection.
The more stabilised chlorine is added, the more stabiliser is added. The disinfecting action of chlorine is blocked and the water is no longer disinfected. This is commonly referred to as “over-stabilisation”.
Reduce the total salinity of pool water (TDS) as well as the risk of corrosion and damage to equipment. Adding calcium to the water with calcium hypochlorite minimizes the risk of corrosion on equipment and installations as well as damage to tile joints.
High-quality water: Calcium hypochlorite makes water crystal clear and healthier.
Enable safe implementation: handling calcium hypochlorite in solid form is simpler and less dangerous for pool maintenance staff compared to chlorine gas or sodium hypochlorite (bleach).
Preserving products for longer: When stored in a cool, dry place with the lid closed, calcium hypochlorite remains effective for 18 to 24 months (depending on the product) from its date of manufacture.

Customer case study

Conversion of an electrochlorination system

A well-known sports complex in Leeds, UK, replaced a salt electrochlorination system with HTH Granular dosed via a system consisting of a dosing pump and a dissolution tank, resulting in:

50% reduction in pH correction costs
An 86% reduction in dissolved salt levels
Lower energy bills
Maintenance operations reduced to twice a year

White water parks

HTH calcium hypochlorite is not just for swimming pools.
In the Middle East, an artificial white water park offering rafting, kayaking and surfing in a 42,000 m³ volume of water switched to HTH to replace a lower-quality chlorinated product.
