“…Furthermore, nutrients from the toilet are diluted by rainwater, groundwater intrusion, and industrial WW. As a result, typical WW consists of more than 95% of water and only 5% of pollutants [4]. Therefore, the current challenge is to rethink the present WW treatment system and provide the technology to not only remove organic and inorganic compounds but also recover them in a sustainable way.…”

In this study, we examined a Chlorella vulgaris-based system as a potential solution to change liquid waste, such as blackwater, into valuable products for agriculture while protecting waters from pollution without technical demanding pre-treatment. To evaluate the possibility of nutrient removal and biomass production from raw blackwater, four blackwater dilutions were tested at lab-scale: 50%, 30%, 20%, and 10%. The results showed that even the less diluted raw blackwater was a suitable growth medium for microalgae C. vulgaris. As expected, the optimum conditions were observed in 10% blackwater with the highest growth rate (0.265 d−1) and a nutrient removal efficiency of 99.6% for ammonium and 33.7% for phosphate. However, the highest biomass productivity (5.581 mg chlorophyll-a L−1 d−1) and total biomass (332.82 mg dry weight L−1) were achieved in 50% blackwater together with the highest chemical oxygen demand removal (81%) as a result of the highest nutrient content and thus prolonged growth phase. The results suggested that the dilution factor of 0.5 followed by microalgae cultivation with a hydraulic retention time of 14 days could offer the highest biomass production for the potential use in agriculture and, in parallel, a way to treat raw blackwater from source-separation sanitation systems.

“…There are numerous methods available for the disposal of wastewater, out of which five methods are widely used, namely, evaporation ponds, deep‐well injection, surface water discharge, disposal into sewers/municipal wastewater, and the concentration of salts and irrigation to salt‐tolerant halophytic plants species (Afrasiabi & Shahbazali, 2011). Generally, selection of the disposal method for the disposal of wastewater depends upon its characteristics, composition, and cost associated with it (Jasim, 2020). The various wastewater disposal methods are described below.…”

Different industrial activities such as agro‐food processing and manufacturing, leather manufacturing, and paper and pulp production generate highly saline wastewater. Direct discharge of saline wastewater has resulted in pollution of waterbodies by very high magnitudes. Consequently, an enormous number of pollutants such as heavy metals, salts, and organic matter are also released into the environment threatening the survival of human and biota. Saline wastewater also has significant effects on survival of plants, agricultural activities, and groundwater systems. Several treatments and disposal technologies are available for saline wastewater, but the selection of the most appropriate treatment and disposal technology still remains a major challenge with respect to the economic or technical constraints. Considering the sustainable management of saline wastewater, the present review is an attempt to compile the existing and emerging technologies for the treatment of saline wastewater. Among all the individual and hybrid technologies, land‐based treatment systems are proven to be the most efficient technologies considering the energy demands, economic, and treatment efficiencies. Likewise, new and sustainable technologies are the need of hour integrating both the treatment and management and the resource recovery factors along with the ultimate goal of the protection in terms of human health and environmental aspect.

Land‐based treatments as the environment friendly and sustainable method for saline wastewater treatment and disposal. Role of phytoremediation in land‐based treatment.

“…Wastewater treatment is a process, which is done on the wastewater to change its quality for drinking or other suitable purposes. Wastewater treatment takes place in wastewater treatment plants, which should be designed under different circumstances (Jasim and Aziz, 2020). These facilities are designed to remove/decrease conventional pollution parameters (BOD5, COD, total suspended solids and nutrients) from the wastewater stream (Edokpayi, Odiyo and Durowoju, 2017).…”

The beverage manufacturer consumed a large amount of clean water in the production process. From the clean water usage in the production process, the manufacturer needs to monitor wastewater discharge from the beverage production. Each beverage company is obligated to monitor wastewater discharge compliance with the Department of Environment (DOE) 's regulations. The quality of wastewater discharge must meet the DOE's pH level requirements, ranging from pH5.5 to pH9.5. Therefore, this study aims to identify the factor contributing to the pH quality of wastewater and understand the effects of wastewater. As beverage manufacturers produce different types of products such as drinking juice, herbal energy drink, carbonated sports drink, tea, and coffee, the quality of wastewater discharge will differ. The study was conducted through an interview to explore in-depth understanding about beverage production and identify the factor related to wastewater quality. Five respondents were selected to participate in the study, and these respondents were of different departments and positions involved in both the production process and wastewater management department. The observation was also made to record and monitor the reading of pH level for few cycle. A few factors were identified in contributing to the pH quality of wastewater such as types of production and methods used to read the pH level.
