Clean water is a basic necessity for daily life. Clean water helps people maintain their daily lives in case of domestic activities. If using unclean water, it will be harmful to the health because water is the medium that transports chemicals and bacteria, viruses, parasites causing diseases that are not visible to the naked eyes. According to statistics, Our country still has many places where the quality of water supply is not ensured for daily life, especially in mountainous, frontier areas and places where the terrain is difficult and lacks of facilities. The water used for living in the northwestern region in general and the Ta Vai stream’s basin in Ha Giang province in particular is taken from rivers and streams that have not been treated or have been processed but the water quality is not guaranteed for living. Therefore, a study on the construction of the treatment model of Ta Vai spring water in Ha Giang province by using membrane technology combined with integrated filter materials for water supply is essential. The research shows that the water treatment model in Ta Vai stream by using membrane technology combined with integrated filter materials has completely treated water as reaching the quality of QCVN 02: 2009 / BYT - National technical regulation on domestic water quality.

Major Consideration

Increasing demand for limited water resources within the Midlands of England resulted in a lower quality river being considered for water supply in an area of high urban and rural population. A comprehensive water quality monitoring programme was undertaken on the river to compare its quality with other sources used for water supply. Concurrent with the monitoring programme a series of laboratory scale trials began to assess how the river water could be treated, and the costs involved. A major consideration was the need to provide treated water by the summer of 1997, which precluded a complete new water treatment process from being designed. The paper outlines the results from the monitoring programme, including some of the problem parameters such as pesticides at over 10 ug/l, and how some of the sources of these pollutants were identified. It also describes the treatment trials and explains how a water treatment process was developed which utilises disused gravel workings to provide bankside storage and a combination of powdered and granular activated carbon to remove organic pollutants.

Water Treatment Process

Nowadays drinking water resource has been polluted, while the conventional treatment process cannot effectively remove polluted matters. In order to tackle this problem, the granular activated carbon (GAC) and ultrafiltration membrane (UF) were introduced into drinking water treatment process. The results revealed that when treat the micro-polluted water the effluent water quality of turbidity, permanganate index and color can reach 0.1NTU, 1.3mg/L-2.3mg/L and 5 degree respectively with GAC-UF process. And the total removal efficiency of turbidity, permanganate index and color can reach 98%-99%, 70%~75% and 60% respectively. The GAC can effectively remove organic matters, while the UF membrane can effectively remove suspended solids, colloids. The GAC-UF combined process can get a good water quality when treat the micro-polluted water.

The need for clean water in big cities is very dependent on water supply by water companies (PDAM). The increasing demand for clean water in big cities is proportional to the increasing of number population and industry, but not comparable to the clean water supply and quality of raw water available. PDAM has made various efforts to improve the quality of clean water services to the community. One of the effort is to improve the performance of water treatment plant (WTP). To support the improvement of the performance of WTP, required water quality monitoring at the intake location in use. This paper discusses the online and realtime water quality monitoring at the water intake location using a multi-probe digital sensor and GSM technology. This observation data is used as a comparative data analysis of laboratory data on raw water source PDAM Taman Kota (Cengkareng Drain). Keywords: air baku air minum, intake PDAM Taman Kota Cengkareng Drain, pemantuan kualitas air, multi probe digital sensor, teknologi online monitoring, Water Treatment Plant

The scarcity of water and increasing water pollution are the pressing challenge human being facing. Recovering water and valuable heavy metals is highly desired for treating heavy metal containing wastewater. We proposed a novel hydrate-based process to treat Ni2+ containing wastewater. The water recovery, Ni2+ enrichment factor, desalination efficiency were studied using this cyclopentane hydrate-based method. A water recovery of 43% can be obtained with a desalination efficiency of round 88% and an enrichment factor of 1.6. The desalination efficiency and the quality of the as-made water via the hydrate-based process can be further improved to above 99% via three-stage hydrate reaction. The proposed hydrate-based water treatment process may find wide applications in waste water treatment and heavy metal recycling.

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.
