Understanding Sodium Hypochlorite | Treatment Plant Operator
When sodium hypochlorite is used, acetic or sulfuric acid is added to the water. An excessive dose can produce poisonous gases. If the dosage is too low, the pH becomes too high, and it can irritate the eyes. The required concentration of sodium hypochlorite depends on the concentrations of pollutants, primarily organic pollutants.
The City of Eagan in North Minnesota, USA required a pump capable of accurately dosing 15% sodium hypochlorite or ‘hypo’ for their new wastewater treatment plant.

(11 -7) Disinfection by Chlorinc and Chlorine Compounds 4'hloriue is available as a liquid, A gas (chlorine) or as chlorine compounds {chlorinated lime, calcium hppochlorite, etc.). Liquid or gaseous chlorine is the preferred form for waste water treatment, because of its lower cost as compared to chlorine compounds.
Standardizing On-Site Hypochlorite Generation Disinfection
In late 2005, the City of Newberg, Oregon, decided to upgrade their water treatment plant disinfection process from gas chlorine to on-site hypochlorite generation (OSHG) in an effort to simplify operations and increase operator safety. The plant produced an average of 2.5 million gallons per day (MGD), with a peak capacity of 5 MGD.
Clean Water Services was able to optimize their dosing operation by installing Grundfos DME dosing pumps. The Situation By optimizing dosing processes, Clean Water Services has reduced dosages of alum and hypochlorite. The former peristaltic and solenoid dosing pumps couldn’t be turned down far enough to deliver the lower dosages.

The City of Eagan in North Minnesota, USA required a pump capable of accurately dosing 15% sodium hypochlorite or 'hypo' for their new wastewater treatment plant. Sodium hypochlorite …
The usual expectation is that the dosing process should be fully automated and controlled so it can be operated and monitored from the plant’s main control room. Sodium hypochlorite, chlorine and dosage. Sodium hypochlorite is a chemical compound with the formula NaCIO. It is composed of a sodium cation (Na+) and a hypochlorite anion (CIO−).
On-site disinfectant production | Grundfos
Vaccuperm chlorine disinfection systems are effective and economical vacuum gas dosing systems for the safe and accurate dosing and control of gaseous chlorine, ammonia and sulphur dioxide. Selcoperm electrolysis systems generate chlorine directly on site with no critical by-products, for the safe and simple production of hypochlorite solution
A new sodium hypochlorite disinfection facility was required to replace the existing gas chlorination disinfection facility at the plant. The new system provides chlorine dosage required for secondary effluent and bypass flow disinfection, RAS bulking control and plant water disinfection. The chlorine is provided in the form of sodium
OSHA Guidance on COVID-19 and Wastewater Treatment
On Feb. 5, 2025, the U.S. Occupational Safety and Health Administration (OSHA) released its new wastewater worker guidance stating that current disinfection conditions in WRRFs, such as oxidation with hypochlorite or peracetic acid, and inactivation by ultraviolet irradiation, are expected to be sufficient to protect wastewater workers and
RE: Sodium Hypochlorite Dosing & Calcium Deposits QualityTime (Civil/Environmental) 30 Dec 13 20:13 The Lake Ontario water I conditioned at my water treatment plant had an alkalinity of 110 mg/L as CaCO3, a hardness of 135 mg/L as CaCO3 and the pH could vary from 7.9 to 8.3.
- What is trichloroisocyanuric acid TCCA used for?
- TCCA: Trichloroisocyanuric acidTCCA can be used in water treatment, especially in swimming pool water treatment, drinking water treatment, algae removing of industrial circulating water, treatment of industrial or city sewage, disinfection of petroleum well drilling slurry and sewage a
- How does TCCA work in a swimming pool?
- Swimming pool water treatment. TCCA can effectively kill bacteria and algae in swimming pool water. At the same time, its decomposition product cyanurate has a stabilizing effect on the effective chlorine in the water, reducing the need to adjust the pH value. Drinking water disinfection.
