Established in 2005 with registered capital 5.97 million USD, focus on the research and development of electrochemical equipment, its brine chlorination system has enjoyed a wide reputation through years, and as National High-Tech Enterprise, Hada's been providing products and service to government, international companies and organizations in more than 26 countries and regions.
Hada's founders were famous research professors in National Research Institues of rare metal, which makes our electrolytic cells almost the best in China, and as its great demand on water treatment industry, it turns many our competitors into our customers. So don't be surprised if you visit other factories' alibaba pages and found machines look like ours, or using our technologies.
HADA is the first manufacturer that produces high concentration sodium hypochlorite generator.
We always keep the best for ourselves and install in the machine, and we never stop processing. Seeing is believing. Welcome to visit us.

High concentration sodium hypochlorite generator produces chlorine gas by membrane electrolysis 25% ~ 30% brine of electrochlorination system, and the gas is sent into the reaction tower for mix reaction with sodium hydroxide, then get the final product of 12% sodium hypochlorite solution;
The system consists of: salt treatment unit, ultra-pure water system, control cabinet, electrolytic unit, reaction tower, absorption tower, sodium hydroxide recycled unit etc.;

1. the diaphragm cell reactions
The power is 2NaCl + 2H2O=H2 +CL2 +2NaOH
Anode: 2Cl – 2e- = Cl2
Cathode: 2H2O + 2e- = H2 + 2OH-
2. The reaction tower:
Cl2 + NaOH = NaCl + NaClO + H2O(NaOH cooling liquid in case)
The high concentration sodium hypochlorite solution is of high oxidation and strong sterilization ability. It is widely used for water treatment in water plant.
1) Fully automatic operation--help reduce the work and cost.
2) Components are all from famous brands--ensure stable running and long service life.
3) Excellent design, flexible capacity arrangement, easy installation.
4) The only one raw material-- salt(food level)-- is safe and easily get.
5) High sefety-- all Cl2 will be reacted with NaOH in the absorption tower without leakage.

It's reasonable that price always stand in a important position when people placing an order, and I'd like to say something about the price.
Let's just take an example of electrolytic cell, you may think the cells are the same if the capacity is same, but do you have any idea about the plating recipe? It really effect the life of electrode!!! And you know how many times we plate? 25 times!!! and some factories may short this or that, which can make their price sometimes increditable low.
So, what do you think ?
You get what you pay for, we can even make a list containbrands, model numbers, specification of every single components, accessories in the equipment to you, just wanna let you know, we are not those companies who lower the price by reducing the quality.
