Title: Effective wastewater treatment/recycling technologies for construction industry—A local experience
Abstract: Publisher Summary
Several types of wastewater are generated and discharged during the construction/demolition period of a site. These various types of wastewater include water from bore piling operation, rainwater and ground water collected, spray water for dust removal, truck cleaning water, and kitchen wastewater. In most of the construction sites, government foul sewers are not connected to the site premises during the construction period hence the different types of wastewater have to be discharged to storm water drain, inland, and coastal waters. In this regard, the quality of discharged effluent is controlled to very stringent limits, such as suspended solids (SS) to 30mg/L, oil and grease to 20mg/L, biochemical oxygen demands to 20mg/L, and chemical oxygen demands (COD) to 80mg/L. Without proper treatment, the discharged wastewater exceed the discharge limits, resulting from not only polluting the environment, but also leading to heavy penalty to the construction companies. This chapter focuses on presenting appropriate technologies tackling different types of wastewater from construction sites. These technologies include effective chemical coagulation and sedimentation system for treating high solids content construction runoff/wastewater from construction activities, and biological wastewater treatment system in continuous operation for treating organic waste bearing wastewater from site office toilets.
