Janjarus Watanachote — 2022-12-22

Objective: The amount of organic substance in Pacific white shrimp pond (Litopenaeus vannamei) will accumulate according to time spent on breeding shrimps. This research studied the morphology and COD (Chemical oxygen demand) reduction efficiency of marine actinomycete Streptomyces indiaensis in order to create a guideline for using Actinomycete in wastewater treatment for coastal aquaculture.

Methods: The morphology of actinomycete S. indiaensis isolated from a mangrove forest was studied using Gram’s staining method and observed under a light microscope. Actinomycete was cultured in standard ISP2 medium and water from a Pacific white shrimp pond. Then, actinomycete S. indiaensis was used to reduce COD in water from the shrimp pond and compared with not using actinomycete S. indiaensis.

Results: Gram’s staining test revealed that marine actinomycete S.indiaensis is filamentous gram-positive bacteria. Marine actinomycete S. indiaensis could grow in a standard ISP2 medium better than in the shrimp pond water. Thereafter, a reduction of the COD in shrimp pond water was performed. The initial COD concentration in shrimp pond water was 662 mg/L. The use of S. indiaensis was able to reduce the amount of COD in the shrimp pond water in a greater manner than without S. indiaensis. The use of actinomycete had complete COD treatment within 21 days, whereas the comparison without the use of actinomycete could be treated at 78%. The results from this experiment showed that a marine actinomycete

S. indiaensis was able to reduce COD faster than the native bacteria in the shrimp pond water.

วัตถุประสงค์:การวิจัยครั้งนี้มีวัตถุประสงค์เพื่อศึกษาการออกแบบ การสร้าง และการทดสอบระบบสูบน้ำด้วยปั๊มขดที่ทำงานด้วยกังหันน้ำ ปั๊มชนิดนี้สร้างง่าย ราคาไม่แพง และบำรุงรักษาง่าย นอกจากนี้ พลังงานสูบน้ำมาจากแม่น้ำ ไม่ต้องใช้เชื้อเพลิงหรือไฟฟ้าสำหรับกระบวนการสูบน้ำ

วิธีการ: The amount of water that can be pumped at a different head of water and the rotational speed of the coil pump when changing the number of coil pumps from 2 sets to 3 sets, each set of coil pumps composed of 6 coils, were studied. The water pumping system in this research consisted of 3 parts: a coil pump, a water wheel, and an oil drum float. The coil pump was 1.1 m in diameter. The coil was made from a hose, with a diameter of 0.0254 m. The water wheel was 1.5 m in diameter. The 10 blades of the water turbine, each of which blade had a semi-circle shape at 0.16 m in diameter, and the length of the blade was 0.8 m, were installed on the water wheel. The oil drum float, used 8 oil tanks with a capacity of 18 liters to make a float for supporting the water wheel and the coil pump, had a total weight of 80 kg. The construction cost was 4,000 baht. In this study, Wang-Nane River, Makluea Mai subdistrict, Sung Noen district, Thailand was chosen as the place to study.

Results: The experimental results showed that at the same head of water, the varied amount of the water pumped depended on the number of coil set. The 3 coil-pump set could pump more amount of water than the 2-coil pump set, while the rotational speeds of the 2 and 3 coil pump sets were not much different. When the pumping height increased, the amount of water pumped decreased. For the worthiness, the break-even point of the water pumping by coil pump working with a water wheel is 6 years.
