Sodium Hypo Plant

 At a target of 100 liters per capital per day, 140 million Nigerians need 14 billion liters of clean water every day!

By WHO standards, for this daily needed volume of water to be safe for Nigerians, about 196,202 liters of chlorine disinfectant at 150 grams per liter strength is needed daily to disinfect at source,14 billion liters of raw water to 2 milligrams per liter (ppm) Chlorine dosage level.

99% of the needed chlorine is imported, with many cases of chlorine adulteration. Hence, several avoidable deaths from water borne diseases are witnessed daily. Such is the state of potable water disinfection today!

The importance of critically needed Chlorine in industries for: wastewater and effluent treatment, household bleach manufacture, boiler water and cooling tower water treatment, textile bleaching, pulp and paper bleaching, oil and gas operations, swimming pools etcetera, can only be imagined. 

Using proven, environmentally sound GE-Ionics/GE Water & Process Technologies Inc. USA patented production technology, WATTCCON is geared towards local commercial production and delivery of high quality 12%-15% strength membrane grade Sodium Hypochlorite (Chlorine Bleach).

Technologies

WATTCCON shall deploy the GE-IONICS Inc USA patented CLOROMAT production technology for the manufacture of its membrane grade Sodium Hypochlorite brand of Chlorine Bleach at 125 ppm Chlorine strength.

The ion exchange membrane process that turns brine to chlorine is currently the most energy efficient and environmentally most acceptable process of commercial chlorine production.

The heart of the GE-CLOROMAT is the chlorine/caustic soda cell module or Ion Exchange Membrane Electrolyser which can generate from brine solution, 5 to 20 metric tones of chlorine gas per day per unit by the equation:

2NaCl + 2H₂O → 2NaOH + Cl₂ + H₂

When CLOROMAT is in Sodium Hypochlorite mode, chlorine gas from the cell module flows into a reaction vessel combining with caustic soda to produce sodium hypochlorite. A heat exchanger removes the heat of reaction and the hydrogen gas produced is vented to atmosphere.

The process of Electrolysis of brine produces Sodium Hypochlorite (NaOCl) and Hydrogen (H2) gas by the equation:

NaCl + H₂O → NaOCl + H₂

The CLOROMAT plant operation and status is controlled via a dedicated Allen-Bradley PLC semi-automatic and manual based interface. All instrumentations are integrated into the PLC control logic.

An 11KVA electrical power supply, a transformer, switch gears and MCC form the power components along with cooling tower and chiller for removing up to 1170 KJ/s of heat from the CLOROMAT system.

A hydrogen gas vent stack, waste effluent treatment and sludge handling system usually compliment the CLOROMAT system together with a chlorine gas scrubber to avoid chlorine gas discharge to the atmosphere.
