This document presents case studies on the water treatment methods for nitrogen components (ammonium) and zinc, which are present in high concentrations in plating wastewater. Since ammonium and zinc are found in high concentrations in plating wastewater, an effective method is to reduce ammonia using ammonia stripping, which volatilizes it as ammonia gas, followed by coagulation and sedimentation treatment for zinc. In cases where ammonia is at a significantly high concentration, it is anticipated that ammonia may remain even after ammonia stripping treatment. Therefore, a combined method is employed, which includes discontinuous point chlorine treatment using hypochlorous acid after the coagulation treatment, achieving treatment to a level suitable for river discharge. The PDF document provides detailed information on the treatment flow. *For more details, please refer to the PDF document or feel free to contact us.*

Factory wastewater and boiler blowdown water often have acidic or alkaline pH values, making it impossible to discharge them as they are. Adjusting such wastewater to a neutral range (around pH 7) is referred to as "pH neutralization treatment." In your factories, you are likely conducting pH neutralization treatment for wastewater such as waste acids and waste alkalis, as well as for coagulation reactions. Generally, two common methods of pH neutralization treatment are observed: ◯ Carbon dioxide method ◯ Chemical addition method This document introduces the various types of pH neutralization treatments and explains how pH neutralization is carried out. *For more details, please download the PDF document or feel free to contact us.

We would like to introduce a case study of the design, construction, and consulting for an electrochemical treatment wastewater treatment facility at a cosmetics factory. Since the factory mainly manufactures shampoo, body soap, and sunscreen (UV), the wastewater contains a high concentration of normal hexane extractable substances. By using electric ions generated to adsorb impurities, we can separate emulsified fats from the wastewater and form flocs (aggregates). By removing these from the wastewater, we can discharge the treated water into the sewer system. Previously, we used a coagulation-sedimentation method for treatment, but since switching to the electrolysis method, we have been able to reduce the amount of sludge generated by 70-80%. 【Case Overview】 ■ Facility: Cosmetics Factory Electrochemical Treatment Wastewater Treatment Facility ■ Biochemical Oxygen Demand (BOD): Raw water 710 → Treated water 370 ■ Normal Hexane Extractable Substances: Raw water 150 → Treated water 3 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where we provided design, construction, and consulting services for a batch reactor type wastewater treatment facility for pig farms' manure and urine treatment. The manure and urine discharged by pigs raised on the farm result in high-concentration wastewater, so we have adopted a natural purification method reactor system for undiluted treatment. This system artificially creates the process by which organic matter turns into soil (self-purification in swamps and lakes) within the reactor tower of the treatment tank and applies it to the treatment of organic wastewater. To save space, this treatment method employs a batch system that allows aeration, sedimentation, and discharge of treated water all within a single tank. 【Case Overview】 ■ Facility Type: Batch Reactor Type Wastewater Treatment Facility for Pig Farm Manure and Urine Treatment ■ Biochemical Oxygen Demand (BOD): Raw Water 7300 → Treated Water 16 ■ Nitrogen Content (T-N): Raw Water 3400 → Treated Water 18 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where we provided design, construction, and consulting services for a fat decomposition wastewater treatment facility at a kimchi manufacturing plant. In this facility, we adopted a fat decomposition system as a pretreatment for biological treatment, which is unsuitable for high concentrations of fats. This system breaks down fats into a form that is easier for biological treatment. For the biological treatment, we employed a contact aeration method that generates less excess sludge and is easier to maintain. In conventional treatment technologies, fats are difficult to decompose and can negatively affect microorganisms, making pretreatment of fats essential through methods such as grease traps and coagulation pressure flotation devices. By adopting the "fat decomposition system" as a solution to many issues, fats are decomposed, eliminating the need for large-scale treatment equipment. 【Case Overview】 ■ Facility: Kimchi manufacturing plant, fat decomposition wastewater treatment facility ■ Biochemical Oxygen Demand (BOD): Raw water 2000 → Treated water 230 ■ Normal hexane extractable substances content: Raw water 150 → Treated water 15 *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a case where we provided design, construction, and consulting services for a coagulation sedimentation wastewater treatment facility at a construction machinery manufacturing plant. The washing wastewater generated during processes such as painting in the manufacturing of construction machinery contains a large amount of heavy metals and phosphorus, which is why this facility employs a coagulation sedimentation treatment method. To efficiently treat the heavy metals and phosphorus contained in the wastewater, lime and coagulants are added to the reaction tank to effectively generate coagulation flocs. Additionally, by adjusting the pH, the generated coagulation flocs are allowed to grow larger, and then, through a sedimentation tank, the flocs are settled by gravity, achieving good solid-liquid separation. The clear supernatant water is discharged as treated water, while the settled sludge is removed from the system in the dewatering process.
