Leave the investigation of the contamination status of the lower collection device and the measurement of the unevenness of filter sand and filter gravel in the filtration pond to us!
At Nishitazaki Kousan Co., Ltd., we conduct comprehensive diagnostics of filtration ponds. If the condition of the filtration layer is left unaddressed, it can affect the quality of the filtered water and accelerate the contamination of the filtration layer, necessitating a complete replacement of the filtration media (layer renewal) in a short period. Therefore, it is essential to conduct regular inspections of the filtration layer and, if abnormalities are found, to immediately take appropriate measures such as improving cleaning methods or replenishing sand.
