Possible applications

KITA Machinery believe local people will be able to continuously install, operate and manage the water treatment system to solve the following situation through our technology transfer, and it leads to promotion of health damage prevention.

 1) Treatment of contaminated water
・Contaminated water with heavy metals such as arsenic and lead
・Construction wastewater
・Industrial wastewater (such as industrial waste recycling plant, food plant)
・Wastewater containing benzene and other aromatic compound
・Wastewater containing dioxin

As it is possible to propose a purification system for contaminated ground water at a waste pile (waste disposal site), it can improve the living environment of people who must use that water.

                                         Fig. 2 Case of the introduction of wastewater treatment facilities

Upper left: Construction site (muddy/turbid water)
Upper right: Industrial plant (water including fly ash)
Lower left: Waste disposal site (wastewater including dioxin, mercury, lead, benzene and arsenic) 

2) Producing clean and safe drinking water from
・River, lake and pond water
・Well water
・Rain water
To prevent endemic diseases by providing clean and safe drinking water.
To reduce environmental load by local production for local consumption of drinking water, instead of buying mineral (bottled) water.

We especially have strengths in water treatment using sand filtration, in the treatment mentioned above. This is one of the most sustainable method in the local in terms of cost and ease of maintenance.

Competitive advantage

Our water treatment is carried out in-house in all processes such as understanding the quality of raw water, selection of chemicals, equipment and operation method, engineering design and installation, therefore we have the necessary technology and know-how for water treatment and we can offer the following.

・Flexible suggestion
We can suggest water treatment method according to the request (budget, use or no use of chemicals, etc.) and the condition of raw water on each site. KITA Machinery possesses essential analytical instruments such as GEO-Rex, XRF, GC-IR, etc. to conduct analysis on site.

・Advanced water treatment technology using sand filtration
We have lots of experience in treating various types of raw water such as producing of drinking water and the treatment of contaminated water with heavy metals such as arsenic and lead by using sand filtration equipped with special backwash system.

・Low initial cost
Equipment and parts will be procured locally as much as possible, so it leads to cheaper initial cost compared to transport all equipment from Japan.

・Know-how at construction site
One of our businesses is the handling of construction equipment in Japan, and we know the conditions of the construction site, therefore we can propose a temporary water treatment. In addition, as we are familiar with the wastewater produced at the construction site (basic aqueous solution including cement or silt), we also have the accumulation of techniques to treat mud water.

Performance

1) Case example at contaminated site with heavy metal in Japan

Treated water volume: 30[m3/hr]
Electricity consumption: approx. 100[kW/hr]
LV: 15[m/hr]

SS(mg/L)】680 (raw water) → < 1 (treated water)
【Dioxins [pg-TEQ/L]】38 (raw water) → 0.071 (treated water)
【Aluminium [mg/L]】0.26 (after application of poly aluminium chloride)　→ 0.085 (treated water)
【Turbidity [ppm]】310 (raw water)→0.2 (treated water) ※by JIS K0101 (turbidity measurement substance: Kaolinite)

2) Case example in the water supply facility in the Philippines

Treated water volume: 420[L/hr]
Electricity consumption: approx. 600[kW/hr]
LV: 8[m/hr]

Turbidity: 0.48[ppm] (raw water) → 0.10[ppm] (treated water)
Total coliform: more than 8.0 (raw water) → less than 1.1 (treated water)
