[미국] 고마쓰, 선진우물처리시설 위해 청정수질시스템 시행

고마쓰 애리조나 시험장(Komatsu Arizona Proving Ground)은 애리조나주 사후아리타(Sahuarita)에 위치하여 660ac의 광산(Mine)에서 당사의 제품에 대한 엔지니어링 테스트 등을 수행하고, 제작에 들어가기 전 프로토타입 장비의 모든 구성 요소를 분석한다.

고마쓰는 선진화된 우물 여과 시스템을 공급하기 위해 애리조나주 투손에 위치한 M3 Engineering&Technology와 공동으로 Clean Water Systems&Stores사를 선정했다.

이 시스템은 양질의 물을 지속적으로 공급할 수 있도록 맞춤 설계되었으며 데미안은 프로젝트를 방문하여 신생 기업을 지원하는 데 큰 도움을 주었다. 유지 보수가 많이 필요한 다른 많은 시스템들과는 달리, 이 시스템은 자동으로 설계되어 유지보수의 필요성이 적다.

Clean Water Systems & Stores는 북미에서 오염된 우물 처리 전문 업체이다. 이 회사는 철, 망간, 모래, 냄새, 박테리아, 탁도 및 퇴적물을 제거하는 시스템을 포함하여 다양한 유형의 설치가 쉬운 수처리 시스템 및 제품을 제공한다.

Komatsu site chooses Clean Water Systems for advanced well water treatment facility

The Komatsu Arizona Proving Grounds is located in Sahuarita, Arizona. AZPG operates on 660 acres of leased Mine property to perform engineering tests and activities on our products, primarily the rigid chassis mining trucks. The Arizona Proving Grounds is responsible for analyzing every component on prototype machines before they go to production.

Komatsu in conjunction with M3 Engineering & Technology Corp of Tucson Arizona chose Clean Water Systems & Stores Inc to supply an advanced well water filtration system to filter and sanitize the water supply from well water source on the property.

Personnel from Clean Water Systems, and M3 Engineering worked together to insure a proper design and installation.

Unlike many systems requiring a lot of maintenance, the system was designed to be low in maintenance and fully automatic. Water from the well is automatically injected with chlorine to kill bacteria and oxidize iron and manganese. The chlorine is injected based proportionally based on the flow of water.
 
After the water is injected with chlorine it flows through a contact mixing tank to allow some time for the chlorine to react with the iron, manganese and any bacteria present. Due to the specially designed chlorine contact tanks, no potassium permanganate is required, as is common with many iron filters. The self-cleaning filtration system uses a special type of manganese dioxide filter media to remove iron and manganese.

As chlorinated water flows through the manganese dioxide filtration system from the well, iron and manganese are removed. The result is crystal clear, odor-free, disinfected water flowing into the storage tank on demand.

After the greensand iron filter the water flows through a zeolite turbidity filter, removing any trace of remaining sediment and turbidity.

The system is set up so after the water has flowed through the filtration system for a set number of gallons, the system automatically shuts down and cleans and regenerates the filters. The system uses a unique process which draws clean filtered water from the storage tank to automatically backwash and clean the iron filters.

This provides proper flow and pressure to clean the iron filter media, and extends the life of the greensand media by using clean water for back-washing and rinse. The entire process is accomplished automatically and requires no routine maintenance, other than periodically adding chlorine to the chlorine pump solution tank.

Demian Ashley, a Certified Water Specialist, and a California Grade II Water Treatment Operator works for Clean Water Systems as a project manager and assisted in the start-up of the new system.

"The system was custom designed to provide a steady supply of high quality water. Demian visited the project and did a great job in assisting in the start-up. This is a system that will last for many years", said Gerry Bulfin, President and General Manager of Clean Water Systems.

Clean Water Systems & Stores specializes in water treatment of contaminated well water in North America and has over 8000 customers in over 40 countries. The company provides custom easy-to-install water treatment systems and products in a large variety of different types and configurations including systems for removing iron, manganese, sand, odors, bacteria, turbidity and sediment.
