Remediation laboratory involves researches in 3 areas as follows:

  •  Development of adsorbents from agricultural wastes for treatment of wastewater containing organic substances and heavy metals/recovery of value metals.
  • Phytoremediation of wastewater/soil contaminated with heavy metals and organic substances by local Thai plant.
  • Removal of color from food industry by local materials.


Our laboratory are concerned to prepare the cheap, specific and high capacity adsorbents for   serving wastewater treatment by adsorption process, which is an alternative way to eliminate all of   heavy metals, organic substances and highly soluble dyes. Accordingly, agricultural wastes (i.e. corncob, coir pith, shrimp shell, macadamia nut-shell, and rice husk) are appropriate to be the raw materials for preparing the special adsorbents for heavy metals, organic substances and dyestuffs. Lab scale and pilot plant are regularly tested and studied to obtain the essential parameters for supporting the operation.

Nowadays, technology for printing  wastewater treatment was developed by remediation laboratory. For example, wastewater treatment of off-set, flexography and screen printing from printing industry as shown in Fig. 1.

Remediation laboratory also emphasized on phytoremediation of wastewater/soil containing heavy metals and organic substances by local Thai plants. In addition, we are selecting the possibility plants that have maximum removal capacity and study on the mechanism of toxic substances uptake by hyperaccumulative plant.

In addition, the research on color removal from food industry by local materials is also studied. The aim is to develop our technology suitable in Thailand.

Service

To consult, design and install the printing wastewater treatment (off-set, flexography and screen printing industry), color treatment (poster color, water colors, rubber-stamp ink, textile printing) and/or heavy metal-contaminated wastewater (electroplating industry). 

In addition, remediation laboratory has service about academic, training and seminar to the entrepreneur and to the public.
