Demineralization System

Demineralization functions to remove lime content (CaCO₃), silica (SiO₂), and salt content, such as magnesium (Mg) and sodium (Na). This system is highly suitable for use in the following industries:

Ultrafiltration System

Reverse Osmosis (RO) System

Available capacities range from 1 m³ to 2,000 m³ per day

WASTEWATER TREATMENT – NO SLUDGE – NO ODOR (Biocleaner)

Biocleaner is a newly patented technology for microbial remediation that can treat waste and wastewater, reducing the Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels to virtually undetectable levels.

Biocleaner bacteria degrade the formed bio-solids, thereby eliminating the need for significant sludge handling. Biocleaner bacteria also metabolize the existing ammonia, effectively resolving ammonia-related issues.

FILTER PRESS

Filter press is a device commonly used to compact sludge or extract liquid from a slurry phase. This allows the liquid to be reused or further utilized.

The filter press is classified as separation equipment that operates on a batching system, where the slurry is pumped intermittently, batch by batch, rather than continuously.

In addition to the Filter Press unit, you may also order individual components or services related to the filter press, including:

WASTEWATER TREATMENT PLANT (WWTP) – ELECTROCOAGULATION SYSTEM

Industrial, hospital, laboratory wastewater treatment, and others…

Advantages of Wastewater Treatment Plant (WWTP) using the Electrocoagulation System:

Available capacity: 5 – 2,500 m³ per day

A modern solution for treating industrial waste and hazardous waste.

BIOFIL SEPTIC TANK

Thick, strong, and durable body material; non-seepage, leak-resistant, long warranty period, and resistant to chemical substances.

Constructed with multiple compartments, equipped with a biofilter, and the outlet quality complies with domestic wastewater quality standards as defined by the parameters set by the Ministry of Environment.

CLEAN WATER TANK

Thick, strong, and durable body material; non-seepage, leak-resistant, long warranty period, resistant to chemicals, anti-moss, and resistant to sunlight exposure, among others.
Suitable for use as a roof tank (for installation on multi-storey buildings).
Providing installation services for panel tanks in small, medium, and large capacities.

OZONE GENERATOR

Ozone generator is used for drinking water sterilization, increasing oxygen content, eliminating bacteria, germs, viruses, and toxins, decomposing metallic hydronium, and breaking down various types of toxic organic compounds contained in wastewater, such as dioxin, benzene, atrazine (Daito, 2000), and different organic dyes (Sugimoto, 2000).

It also eliminates various microorganisms such as Escherichia coli, Salmonella enteritidis, and various other pathogens (Violle, 1929).
Capable of inhibiting fungal growth (Kuprianoff, 1953) and Botrytis cinerea fungal on vegetables and fruits (Barth, 1995).
