Clean drinking water must be available to stop the spread of numerous watertransmissible diseases.They can create biological poisons, chemical odors and tastes when exposed certain environmental circumstances (Abd El-Hady, 2014).In terms treatment authority, algae are crucial, particularly those from cyanobacteria family (Lei et al., 2021).Additionally, they hinder several procedures, reducing amount potable produced.Due their silicon frustules, diatoms frequently block filters.(Ahmed, 2016; Abouzied, 2021).Algae have few inhabitants scattered throughout lakes rivers, but nutrients become more plentiful in surface waters, population is vulnerable fast growth (Al-Jadabi 2023).This may cause oxygen atmosphere decline turbidity increase, degradation aquatic environment, as demonstrated by Shen al.

The issue of water contamination has gotten worse worldwide due to industrialization and population increase. wastewater discharge techniques used by Ethiopia's textile sector do not comply with the national standard. Because inadequately treated or untreated effluent into environment is becoming more frequent. Thus, minimizing this trend's harm requires using best treatment technology. Coagulation considered one most effective methods for treating wastewaters, which technically need have a natural artificial coagulant added eliminate dangerous pollutants. Nonetheless, criticism been leveled against use chemical coagulants their serious disadvantages. This led an interest in substituting materials coagulants. main objective study was evaluate compare effectiveness various powders Moringa seed cactus pad when employed as clean up effluent. seeds consist proteins (cationic dimeric) help neutralizing absorbing colloidal charges containing suspended solids. To examine impacts operating parameters, including dose, pH, mixing time, well ideal coagulation conditions, experiments were conducted jar testing system. parameters pH 4, 5 g/l coagulant, 40 min 2 fast at 100 rpm, gradual 30 settling time. Under these circumstances, 82.33 Moreover, powder reduced turbidity 53.16 %, TDS 97 BOD 58.75 COD 25.37 Conductivity 60 TSS 56.33 %. Therefore, Cactus advised. Rather than seed, it efficiently eliminates turbidity, TDS, from effluents sector. Eventually, process, pad, proved be useful chosen.

In this study, two by-products resulting from the processing of cherry (stems and pits) were used as natural coagulants to promote valorization these wastes treat olive mill wastewater (OMW). The efficacy plant-based (PBCs) in coagulation–flocculation–decantation process (CFD) was evaluated through removal turbidity, total suspended solids (TSS), polyphenols (TPh), dissolved organic carbon (DOC). CFD demonstrated be effective turbidity TSS reduction OMW. Using stems (CSs), reductions 65.2% 58.0% TSS, while pits (CPs) achieved higher reductions, 78.6% 68.2% TSS. To improve effectiveness OMW treatment, mainly regarding TPh DOC, complemented with adsorption (using bentonite clay). capacity acidic conditions (pH 3.0) and, a dosage 3.0 g L−1, reached 17.3 mg DOC 13.8 per gram bentonite. Several isothermal models assessed, Langmuir (r2 = 0.985), SIPS 0.992), Jovanovic 0.994) provided best fittings. According optimal operational defined throughout present work, combination removals follows: (1) 98.0 91.3% (2) 80.8 81.2% (3) 98.1 97.6% (4) 57.9 62.2% for CSs CPs, correspondingly. Overall, results suggest that can low-cost when combined another natural, abundant, cheap material, such clay, sustainable alternative treating

While for example, is naturally occurring has no known health hazards when used in right amount treatment, there growing concern about sustainability environmental impacts these inorganic coagulants. To explore a cost-effective, sustainable, eco-friendly alternative, we investigated shell calabash fruit (Crescentia cujete) as plant-based natural coagulant. Although plant been extensively studied its medicinal purposes this first report potential use coagulant treatment. Using Jar Test experiments statistical analysis, found that obtained from Crescentia cujete was able reduce by 84.3% at an optimal dosage only 1.0 g/L.
