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." I believe that in your factories, you are also conducting pH neutralization treatment for wastewater such as waste acids and waste alkalis, as well as for coagulation reactions. This document introduces the various types of pH neutralization treatments and the mechanisms by which pH neutralization is carried out. Please feel free to download and take a look.

"Normal hexane extract substances" are mainly considered indicators of oils, including animal and vegetable fats such as salad oil, as well as mineral oils like oils. In particular, in food manufacturing and processing plants, as well as cosmetic manufacturing and semiconductor manufacturing plants, wastewater containing a high concentration of "normal hexane extract substances" is generated. If discharged without treatment, it can cause pipe blockages, corrosion, and unpleasant odors, making proper treatment essential. This document provides a brief summary of commonly used methods for treating normal hexane extract substances. It is a resource that clearly outlines the "principles" and "advantages and disadvantages" of each method. Please feel free to download and review it.

A "specific facility" refers to facilities installed at factories or business establishments that discharge wastewater or waste liquids, as defined by government ordinances or regulations. (1) Those containing substances that can harm human health (hazardous substances) (2) Those that may cause damage to the living environment (living environment items) Among the ordinances related to water quality regulations, there are also ordinances that differ by region. Here, we introduce the laws and ordinance regulations applicable to business establishments in Shiga Prefecture. 【Water Quality Regulation Laws and Ordinances in Shiga Prefecture】 - Water Pollution Prevention Act - Ordinance establishing discharge standards based on Article 3, Paragraph 3 of the Water Pollution Prevention Act (additional ordinance) - Shiga Prefecture Pollution Prevention Ordinance (Pollution Prevention Ordinance) - Shiga Prefecture Ordinance on the Prevention of Eutrophication of Lake Biwa (NP Ordinance) - Lake and Marsh Law - Sewerage Law Our company responds to inquiries regarding the Water Pollution Prevention Act, Shiga Prefecture Pollution Prevention Ordinance, NP Ordinance, etc. We can also support you from planning and drafting to execution on how to address wastewater issues.

Our company utilizes know-how based on extensive experience and achievements to handle the design, construction, maintenance, water quality analysis, and consulting for wastewater treatment facilities in various factories. Currently, we are offering a "document" that introduces various services related to water treatment and includes case studies of wastewater treatment specific to different factories, such as cosmetic factories and meat and seafood processing plants. [Featured Case Studies] - Kimchi manufacturing factory (fat decomposition type waste treatment facility) - Cosmetic factory (electrolytic treatment type waste treatment facility) - Construction machinery manufacturing factory (coagulation sedimentation type waste treatment facility) - Meat and seafood processing factory (contact oxidation-biological treatment type waste treatment facility) - Pig farm waste treatment (batch reactor type waste treatment facility) You can view this information in the related catalog.

Our company provides comprehensive support for wastewater treatment facilities in various industries such as semiconductors, cosmetics, and food, covering "design and construction," "maintenance and repair," and "water quality analysis." The content of water treatment equipment varies at each site. We will consider various technologies and make proposals that are more suitable for each specific site. Please feel free to contact us when you need our services.
