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