Effectiveness of Available Wastewater Treatment Facilities in Rubber Production Industries in Sri Lanka

Disni Gamaralalage, Osamu Sawai, and Teppei Nunoura
Abstract—Rubber is a historical crop in Sri Lanka and now Sri Lanka is one of the leading rubber producers in the world. Even though rubber production is a well-established industry in the country, treatment of wastewater from rubber production plants is still an ongoing issue. Most of the industrial scale rubber production plants are equipped with wastewater treatment facilities. But small-scale rubber producers who cover 77% of country’s rubber production have no available treatment facilities for wastewater from their rubber production. Also not enough research has been conducted for identifying effectiveness of currently applied treatment facilities to treat rubber wastewater in Sri Lanka. This study focuses on identifying the characteristics of Sri Lankan rubber wastewater and effectiveness of available wastewater treatment facilities in rubber production plants in Sri Lanka. Assessing efficiencies of applied wastewater treatments was performed by analyzing the characteristics of influents and effluents of treatment facilities. The characteristics of rubber wastewater and current situation of applied treatments were identified in the study including high inefficiencies in removing nitrogen in wastewater to required limit.

Index Terms—Chemical oxygen demand, rubber wastewater, Sri Lanka, wastewater treatment.
